Model Selection Table DESCRIPTION The SP207E-SP213E are enhanced transceivers intended for use in RS-232 and V.28 se- rial communication. These devices feature very low power consumption and single-supply operation making them ideal for space-constrained applications. Exar-patented (5,306,954) on-board charge pump circuitry generates fully compliant RS-232 voltage levels using small and inexpensive 0.µF charge pump capacitors. External +2V and -2V supplies are not required. The SP211E and SP213E feature a low-power shutdown mode, which reduces power supply drain to µA. SP213E includes two receivers that remain active during shut- down to monitor for signal activity. The SP207E-SP213E devices are pin-to-pin compatible with our previous SP207, SP208, SP2 and SP23 as well as industry-standard competitor devices. Driver output and re- ceiver input pins are protected against ESD to over ±5kV for both Human Body Model and IEC000-4-2 Air Discharge test methods. Data rates of over 20kbps are guaranteed with 230kbps typical, making them compatible with high speed modems and PC remote-access applications. Receivers also incorporate hysteresis for clean reception of slow moving signals.
